Description
</h2>
<CODE>net = knn(nin, nout, k, tr_in, tr_targets)</CODE> creates a KNN model <CODE>net</CODE>
with input dimension <CODE>nin</CODE>, output dimension <CODE>nout</CODE> and <CODE>k</CODE>
neighbours.  The training data is also stored in the data structure and the
targets are assumed to be using a 1-of-N coding.

<p>The fields in <CODE>net</CODE> are
<PRE>

  type = 'knn'
  nin = number of inputs
  nout = number of outputs
  tr_in = training input data
  tr_targets = training target data
</PRE>
